ELI5 why does this give “false”?
Discussion
The "in" keyword checks the presence of keys, not values. The array has keys 0, 1, 2, 3. Basically "in" does not do the same thing as Python. l.includes(4) is true.
ohhh, interesting, thank you so much for the explanation 💜
so that’s why a string is also a key and considered true in this scenario then? 🤔
